The online access might be fun, have not had much use for it yet.
My plan has always been to use open source for online / web based services because of the very high costs of ESRI server software.

If you are just exploring then by all means use the HOME license '''not the developer license'''. The desktop software

After you have created a '''relationship class''' (which requires Standard or Enterprise license)
then you can see related information in the attribute table in ArcMap. Select something and
use the "related table" button in the top bar of the attribute table window to pick which table you want to view.


==== Arcobjects containers ====
A good working example is using a taxlot polygon feature class, which has only the taxlot identifier as an attribute;
all attributes are in related tables. For example there is a tax assessor table, a sales history table, and so on.


You can group tools for ArcCatalog into toolboxes called .tbx files.
The sales history table is a good example of a one-to-many relationship. One taxlot may have been sold many times so there will be a separate row in the sales history to record each sale.
This is just a convenient way to handle them as groups in the ArcToolbox UI.
The tools themselves still live in their .py files.


==== Sample ArcObjects applications ====
You can also drill down with the "identify" tool in ArcGis Desktop to see related information, here is a picture.
You can see the taxlot id "12509...." is used to relate the parcel to the Main table, and then Main relates to other tables;
I have expanded Improvements and you can see there have been 3 recorded improvements on this property.

open the file in PythonWin 2.4

2018-Feb I ended up buying a developer license last summer, and IMO it was a waste of money. It was a success in that I was able to spend enough time with it to become convinced it has very little to offer a small organization or individual consultant. I should have continued to push forward with PostGIS and the rest of the FOSS stack. Life goes on. If you have an employer insisting that the ESRI server stack is the only way to go (as I currently do), good for you, someone else can bear the cost and responsibility for the decision.

2014-Mar-20 At the end of the month, I will be leaving my day job as a c# programmer, giving me more time to do GIS! I will be losing access to my EDN (ESRI Developer Network) resources.

What can I do with the "ArcGIS for Home Use" license?

What is "ArcGIS for Home Use"? See http://www.esri.com/software/arcgis/arcgis-for-home Do they still call it "home" or is it "personal"? I can never keep all the product name changes at ESRI straight. OH! and I think it's changed to "Esri" now. Not ESRI.

Joins and relates

Joins only work right if you have a one-to-one cardinality between your spatial and table data. If you have other cardinalities you have to use a relate or a relationship class.

After you have created a relationship class (which requires Standard or Enterprise license) then you can see related information in the attribute table in ArcMap. Select something and use the "related table" button in the top bar of the attribute table window to pick which table you want to view.

A good working example is using a taxlot polygon feature class, which has only the taxlot identifier as an attribute; all attributes are in related tables. For example there is a tax assessor table, a sales history table, and so on.

The sales history table is a good example of a one-to-many relationship. One taxlot may have been sold many times so there will be a separate row in the sales history to record each sale.

You can also drill down with the "identify" tool in ArcGis Desktop to see related information, here is a picture. You can see the taxlot id "12509...." is used to relate the parcel to the Main table, and then Main relates to other tables; I have expanded Improvements and you can see there have been 3 recorded improvements on this property.

Autocad

There are web-based tools you can use now provided by Autodesk for working with CAD files. If you have the Data Interop tools you can work with them in there too.

Bookmarks

As of ArcGIS 9.x you can load and save bookmarks in files now, of course in yet another undocumented file format. (ESRI have heard of GPX and XML and KML but have not embraced them yet.)

ArcObjects

I used to have information on ArcObjects and ArcGIS Engine here. Since I am no longer programming c# (ever again if I can help it) I have removed this information. I am not interesting in doing more ESRI based desktop applications or extensions in the .Net environment.

Python runs EVERYWHERE. C# runs in .Net Microsoft environments or in Mono. I don't like C# enough to want to mess with Mono.

Method to insert data entry forms

Eric O’ Neal

Make a new project, or open the macro editor of your old one, and add the form. After that, go back to the map and right click somewhere in one of the grey toolbars. Scroll down to 'Customize'. Click the 'Commands' tab at the top and change the "save in:" to 'your project' (not ' Normal.mxt'. In the left box, scroll down to 'UIcontrols'. Click 'New Control'.->>'Button Control' Drag the new button to a toolbar. Right click the new button and select 'View Source'. You will see the click event. type in:

'frm1.show'

The button should work now. You can make new Toolbars in the 'Customize' part and drag this button on to them if you want.

Lawrence Hartpence

The way that I have brought data entry forms into ArcGIS is by adding UIControls. In ArcMap, go to the "Tools" menu and then select "Customize". Select the "Commands" tab and scroll down to the "UIControls". After you select "UIControls", three buttons will appear below the pick list, click on the one that says "New UIControl..." A window will pop up with an array of different controls you may create. Choose new UIButton Control. Once this control is created, you will see it in a pick list on the Right side of the "Customize" window. Click on the new UIButton control and drag it to one of the toolbars. Once on the toolbar, right click on the button and in the menu which Pops up, choose "View Source". This takes you to VBA. You access the form by typing the form's name Then ".show (0)" in the Sub which is automatically set up for your UIButton control. It will look something like this: Private Sub UIButtonControl1_Click() QueryForm.Show (0) End Sub

Nick Seigal

(1) VBA is embedded in ArcGIS. You can access the Visual Basic Editor from the Tools menu. VBA has its own forms engine that is different from that in VB (more on that later). Much like in Excell or Access, you can create code and even forms that run like macros. These can be added by hand to the interface of a map document or even to the Normal template (so that they are available in all new Map Documents).

(2) VB6 is often used (although you could also use VB.Net, C++ or C#) to create what is called an "extension" to ArcMap. An example of this approach are ESRI's own extensions, such as Spatial Analyst. To add functionality to ArcMap in this way requires fairly advanced VB skills, although there are many small and fairly easily tweaked samples that you might get to work without having to mess with the extension sturcture. All you would need to do is have the Visual Basic 6 development environment on your machine and take an ESRI sample, add the VB form and data editing functionality you want to that extension framwork and compile the extension as a .dll file. Then, when this file is registered with Windows and with the ESRI COM Categories (ESRI Add Ins to VB6 help with these tasks), the fuctionality will Appear like magic in ArcMap.

(3) Model Builder can be used to create tools for ArcToolbox that use form-like interfaces and which do basic editing tasks. Check out the documentation on that tool for more details.
